You can leave it docked onto the meter to collect blood or, if you prefer, you can undock it. Test strip drum instead of individual test strips You never need to touch a test strip. Simply insert a drum with 17 test strips into the meter. Easy to operate Turn the meter on, apply blood, read the result, press the button to eject the test strip. Automatic-coding Every test strip drum has its own bar code. The meter is automatically coded whenever you insert a new drum, a process which provides the meter with information on the specific characteristics of the test strips. Indication of the number of test strips remaining Each time you turn the meter off, it shows you the number of test strips remaining in the drum. 16 Introduction Reliability The meter checks each test strip. If it finds a defective strip, it lets you know before you apply blood. Blood volume checking The meter can tell when you have applied sufficient blood (approximately 1.5 μL (1 microlitre = 1 thousandth of a millilitre)). It waits until then before starting the test. If the test does not start, you may apply more blood. Alarm clock function The meter can remind you to test your blood glucose. You can set an acoustic signal to remind you at three different times. Hypo indicator function In order to look out for unusually low results you can set a hypo indicator level (hypo threshold). If a result is below the level you have set, a symbol in the display and an acoustic signal (provided it is set to on) prompt you to check your result carefully to see if you are heading towards a possible hypo (low blood glucose). Downloading data to a computer The meter has an infrared window. You can download results to a computer running the appropriate software or to special analysis systems. Introduction 17 1 Acoustic Mode 1.4 Acoustic Mode is intended for persons who are visually impaired. When Acoustic Mode is turned on, the meter guides the user through the blood glucose test using beep tones; it also outputs the result as a series of beeps. For more information see Chapter 6. Throughout this Reference Manual you will see examples of what the display looks like. Any elements that are shown surrounded by a halo in these examples flash in the display. Visually impaired persons need a sighted person to instruct them in the use of the meter and to assist them with all aspects of its operation. Visually impaired persons must not test their blood glucose without assistance from a sighted person. Display illustrations Example: You have turned on the meter to perform a blood glucose test. In the display you see the time and date plus the test strip symbol and the drop symbol. The test strip symbol and drop symbol are flashing. The time, date and blood glucose results shown in the display illustrations are intended only as examples. The numbers will not necessarily be the same as those shown by your own meter. The meter that is used for illustration in this manual displays blood glucose results in mmol/L (see Chapter 2.2) and has been set to 24-hour format (see Chapter 3.6). Your meter, on the other hand, may show blood glucose test results in mg/dL and/or be set to 12-hour format. 18 Introduction Introduction 19 2 Initial steps before testing 2.1 Checking the contents 2 2.2.1 Type plate Check that your monitoring kit is complete. The package contents are listed on the box. The type plate on the back of your meter indicates which unit of measurement your meter uses. If anything is missing, please contact the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1800 709600 (Ireland). 2.2.2 Display check 2.2 You can check the unit of measurement your meter uses by performing a display check. Checking the blood glucose unit Blood glucose results can be displayed in two different units of measurement (mmol/L or mg/dL). Consequently, Roche sells two different versions of the same meter. If you do not know which is the right unit for you, ask your doctor. The unit of measure normally used in the UK and Ireland is mmol/L. Press and hold down the M button. The meter turns on. While you hold down the M button, you first see the display check. mmol/L meter or mg/dL meter Check that your meter displays the unit that is right for you. Check the unit by referring to the type plate and to the display window during a display check (see the following pages). Note The unit that your meter displays cannot be changed. If the wrong unit is printed on the type plate, please consult your dealer or pharmacy. Using the wrong unit can cause you to misinterpret the test results. 20 Initial steps before testing The unit of measurement is shown in the bottom right corner of the display. Initial steps before testing 21 2 If you continue to hold down the M button, you then see the following display after approximately 2 seconds. mmol/L meter mg/dL meter Notes i If additional lines appear during the display test or parts of the numeric field or of a symbol are missing, please contact the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1800 709600 (Ireland). If the numeric field (mmol/L meter) or (mg/dL meter) is affected, the meter may not show your test results correctly. i The meter automatically turns off after 60 seconds even if you keep the M button pressed. i You can perform a display check whenever you wish. If there are results already saved in memory, the most recently saved result is displayed when you release the M button. or When you release the M button, your meter is in memory mode. As long as no results have yet been saved, three bars are displayed. Press the Test button to turn the meter off. 22 Initial steps before testing Initial steps before testing 23 2 2.3 Inserting or replacing the test strip drum If your meter is brand new and unused, it will contain a mock drum (an empty drum without a label), which you must remove and replace with a test strip drum. Read the package insert that came with the test strip drums. If the meter is on, press the Test button to turn it off. Wait for the motor to stop. Set into the bottom of the meter to the left of the finger pricker is a recess. The upper part of this recess belongs to the drum compartment cover. Hold the meter in your right hand and place the thumb of your left hand into this recess. Then pull the drum compartment cover with your fingers slightly to the front and lift it up. Drum compartment cover Irrespective of whether a test strip drum is inserted or not: Recess Press the red drum release button. 24 Initial steps before testing Initial steps before testing 25 2 The pin holding the test strip drum in position retracts with an audible CLICK. Insert a new test strip drum in the meter as illustrated (the two rows of bar code must be nearest the display window). Close the drum compartment cover and push it shut. There will be an audible CLICK. The meter turns on and rotates the test strip drum until the first test strip is in the correct position. At the same time the meter reads the bar code that provides it with information on the specific characteristics of the test strips. After that, the meter turns off. If there is a test strip drum in the meter: Tip the meter forwards. The test strip drum drops out. 26 Initial steps before testing Initial steps before testing 27 2 A dot appears in the small control window on the back of the meter. This indicates that you have just inserted a test strip drum. When you perform a blood glucose test, the meter counts the number of test strips that you have used. The number of strips remaining is displayed in the control window. If you do not insert a new drum, the following message appears the next time you turn on the meter: H> and the drum symbol are flashing to indicate that the test strip drum is empty. Notes When all the test strips in a drum have been used up, the dot reappears in the small control window. Use only test strips that are not beyond their expiry date.Test strips that have expired can produce incorrect results. Incorrect results can cause the wrong therapeutic decision to be taken and so produce serious adverse health effects. The expiry date is printed on the pack and on the peel-off label on the drum container next to the symbol. Insert a new test strip drum. 28 Initial steps before testing Initial steps before testing 29 2 New test strip drums where the aluminium foil (the silver ends) is damaged cannot be used. Your blood glucose results may be incorrect if you use a damaged drum. Incorrect results can cause the wrong therapeutic decision to be taken and so produce adverse health effects. Only open the drum compartment cover when the meter is turned off and the motor is not running. Opening the drum compartment cover when the meter is turned on may result in damage to the meter. i Handle the test strip drums with care! Only remove a test strip drum from its container when you intend to use it. The container protects the aluminium foil on the drum from damage. i There is a label on every drum container. The left portion may be peeled off. On it is the concentration table for the Accu-Chek Compact Autocontrol control solutions. The stated concentrations are valid only for the test strips contained in this drum. You need this table for the performance check of your meter (see Chapter 7). You may, for instance, wish to stick the peel-off label in your notebook or diary. When conducting a performance check, always check that the peel-off label with the concentration table belongs to the test strip drum that is currently in the meter. 30 Initial steps before testing i If you insert a partly used drum in the meter, the meter rotates the drum so the dot appears in the control window on the back. When you subsequently turn on the meter to perform a test and ... " ... you have re-inserted a same drum you previously removed: The meter immediately rotates the drum to the first chamber that contains a test strip, and ejects the strip. " ... you have used up the previous drum or have replaced one partly used drum with another partly used one: The meter may search all chambers until it finds the first one that contains a test strip. The fewer test strips the drum contains, the longer the process takes. If the meter immediately rotates the drum to one of the chambers near the end (you can tell by the noise of the motor that rotates the drum), the drum may ultimately still contain test strips even though the meter regards it as empty. You can still use the test strips by inserting the drum again. Initial steps before testing 31 2 If you insert a partly used test strip drum into the meter, the meter cannot calculate the use-by period for that drum. Consequently, the next time you perform a test, the drum symbol and flashing bottle symbol are displayed to highlight the fact (see Chapter 2.3.1). 2.3.1 Test strip drum use-by period i Use only Accu-Chek Compact test strip drums. Other test strips cannot be used to perform tests. If you insert a different test strip drum, error message E22 is displayed (see Chapter 12.2). Once a drum has been in the meter for 90 days, its use-by period has expired. The next time you turn the meter on to perform a test, the drum symbol, bottle symbol and clock symbol are displayed to highlight the fact. i Make sure that the drum compartment cover is tightly closed. If it is not properly closed, the meter will not turn on when you press the Test button. All you see is the display check briefly. i You can dispose of used test strip drums with your regular household waste. i When you insert a new drum into the meter, the meter starts to count the number of days the drum is in the meter. Each drum must be used within a 90-day use-by period. Insert a new test strip drum. Note The test strips in this drum cannot be used. You must not use these test strips as they may produce incorrect results. Incorrect results can cause the wrong therapeutic decision to be taken and so produce serious adverse health effects. 32 Initial steps before testing Initial steps before testing 33 2 The meter is unable to calculate the 90-day use-by period if " you insert a partly used drum in the meter, even if it is the same one you have just removed, " Flashing test strip and flashing drop, indicating that you may now apply blood or control solution " Drum, indicating that the use-by period cannot be calculated " the year, date and time settings are lost when you replace the batteries (see Chapter 9), and a partly used drum remains in the meter. " Flashing bottle, prompting you to perform a performance check in order to check the test strips The meter has no way of telling you in these cases when the drum was first inserted or how long the partly used drum has already been in the meter. Perform a performance check (see Chapter 7). If the meter cannot calculate the use-by period and you turn the meter on to perform a test, the following symbols appear in the display: If the result from the performance check is within the stated concentration range, you can still use the test strips remaining in the drum. If the result is outside the range, you need to insert a new drum. Following the performance check, the bottle symbol disappears from the display. If you do not perform a performance check, the flashing bottle symbol appears with every test until you insert a new drum. The drum symbol continues to be displayed with each test in order to draw your attention to the fact that the meter cannot calculate the use-by period. All results are saved along with the drum symbol. The drum symbol only disappears when you insert a new drum. 34 Initial steps before testing Initial steps before testing 35 2 2.3.2 Indication of the number of test strips remaining Each time you turn the meter off with the Test button, it shows you the number of test strips remaining in the drum. The number of remaining strips continues to be displayed as long as you hold down the Test button. In this example there are still 12 test strips in the drum. i If you have not performed a test since last replacing the drum, the meter cannot tell how many test strips there are left in the drum. This is e.g. the case when, after you have changed the drum, you start by changing settings or retrieve results from memory. If you then press the Test button to turn the meter off, only three horizontal bars are displayed instead of the number of test strips remaining. Only when you have performed a test with the newly inserted drum does the meter display the number of test strips remaining each time you turn the meter off with the Test button. When you release the Test button, the meter turns off. Notes i If the test strip drum contains three or fewer test strips following a test, the number, the test strip symbol and drum symbol flash in the display window. i If you press the Test button only briefly when turning the meter off, the number of test strips remaining is displayed only briefly or not at all. 36 Initial steps before testing Initial steps before testing 37 3 Settings You can change the settings of your meter to turn the beep tone or Acoustic Mode on or off, to set the brightness of the display, to select the time-and-date format, to set the year, the time and the date, and to activate the alarm clock function and the hypo indicator. When you turn the meter on for the first time, it has the following presettings. These are factory defaults that you can change. " Beep tone on, Acoustic Mode off " Brightness of the display: medium Beep tone: When the beep tone is set to on, it provides user support during testing by marking the start of each step acoustically. Acoustic Mode: When Acoustic Mode is turned on, the meter guides you through the blood glucose test using beep tones; it also outputs the result as a series of beeps. " Year: current year, e.g. 2007 " Time-and-date format: 24-hour format; 24-hour format is associated with the date format day-month (DD-MM) " Time: current time based on Central European Time Alarm clock function: You can set the meter to remind you to test your blood glucose. " Date: current date based on Central European Time Hypo indicator: You can set a personal hypo indicator level. If your result is below this level, the meter alerts you to the fact that you are possibly heading towards a hypo. " Hypo indicator off The meter is supplied with batteries already inserted. The time and date are already set. You may need to adjust these settings to your own time zone. " Alarm clock function off Notes i You can perform blood glucose tests without adjusting any of the settings. All settings are the default factory settings (see next page). 38 Settings Settings If the year, time and date settings were lost as a result of a battery replacement (see Chapter 9) and you fail to reset these, the meter displays the time as 0:00 and the date as 0-00 (in 24-hour format as well as in 12-hour format) when you perform a test. In memory the results are saved not with the time and date but with their memory location number (see Chapter 5.2). Without the time and date the meter is not able to calculate averages, nor the lowest and the highest values (see Chapter 5.3). Results sent to a 39 3 PC, for instance, without the time and date (see Chapter 5.4) cannot be statistically analyzed or, if they can, then only to a limited extent. i The descriptions of settings proceed in the order in which they appear in the meter. If the year, date and time settings are lost as a result of a battery replacement, the meter displays the following settings: Beep tone or Acoustic Mode Brightness of the display Year Time-and-date format Time Date Alarm clock function Hypo indicator " Year: year of manufacture 20XX, e.g. 2007 " Time: 0:00 or 12:00 a.m., depending on the time-and-date format you selected previously " Date: 1-01 as day-month (D-MM) or month-day (M-DD), depending on the time-and-date format you selected previously 3.1 Changing settings – General rules The appearance of in the display window indicates that the meter is in settings mode and that you can change these. In the sections set out below you will find " a description of the general rules for changing settings, " descriptions of individual settings and how to change them. 40 Settings Settings 41 3 The procedure for changing the settings is as follows: " The settings have a fixed sequence and are displayed consecutively, see illustration on the previous page. " Press the S button to call up the settings. A test strip is not advanced. " Press the M button to change the setting that is currently flashing. Numbers such as the year are incremented by one. Pressing and holding down the button increments the number quickly. " From the last setting “Hypo indicator” pressing the S button takes you back to the first setting “Beep tone/Acoustic Mode”. " You can close the settings at any time by pressing the Test button. All settings you have entered up to that point are saved. Notes i Always turn the meter on with the S button when you intend to change the settings. Instead, if you turn the meter on with the Test button and there is a drum in the meter, a test strip will be advanced. i If you turn the meter off with the Test button, it shows you the number of test strips remaining in the drum (see Chapter 2.3.2). i The meter turns off automatically after approximately 60 seconds if you do not press a button. All settings you have confirmed up to that point with the S button are retained. Settings that you have not confirmed with the S button are lost and the original setting remains. From the highest selectable number, pressing the M button automatically takes you to the lowest one. In the case of settings where there are a number of options, such as the beep tone setting, pressing the M button presents each option in turn. " Press the S button to save the chosen setting and move on to the next setting. " You can change any setting at any time. Press the S button repeatedly until the setting you wish to change is displayed flashing. 42 Settings Settings 43 3 3.2 Turning the meter on 3.3 3 Setting the beep tone or Acoustic Mode You are here Beep tone or Acoustic Mode Brightness of the display On / Off / Acoustic Mode Low / Medium / High Time Date Alarm clock function Hypo indicator Hours, Minutes Month, Day Off / 1, 2 and 3 (hour, min) Off / Level Year Time-and-date format 24-hour / 12-hour This setting enables you to turn the beep tone on or off and to activate Acoustic Mode. When the beep tone is turned on, you hear a beep during testing With the meter turned off, press the S button. " when the meter is ready to test so you can draw up blood or control solution with the test strip, The meter turns on without advancing a test strip. Following the display check (see Chapter 2.2.2) the current beep tone setting (symbol ) is flashing. " when the test strip has drawn up sufficient blood or control solution and test has started, " when the result is displayed, " when the hypo indicator is turned on and the result is below the level you have set, " when the meter displays an error message. 44 Settings Settings 45 There are two types of beep tone, differing in pitch. The pitch for a hypo indicator or an error message is higher than that heard in the other cases listed above. When Acoustic Mode is turned on, the meter guides you through the blood glucose test using the beep tones mentioned above; it also announces the result as a series of beeps (see Chapter 6). The beep tone is factory-set to on (H). Press the S button to save the chosen setting. The brightness setting comes next. Notes i When you select Acoustic Mode H, you hear a beep. i The beep tone setting has no influence on the alarm clock function. If you have turned the alarm clock function on (see Chapter 3.9), the meter will always beep to remind you to test your blood glucose even if the beep tone itself is turned off.

Therefore we recommend leaving the hypo indicator function turned off when using the meter in a professional setting. See chapter 10 for more information. 69 4 Testing blood glucose 4.1 Preparing to test blood glucose You can choose one of 11 different penetration depth settings to suit your own skin type. You can use the finger pricker either docked with the meter, or undocked. You will need the following items to carry out the test: " the meter with a test strip drum inserted " the finger pricker to obtain blood The finger pricker has a plunger at the top (see illustration in Chapter 1.2). This plunger has three functions: " a lancet for the finger pricker " priming the finger pricker Wash your hands with warm water and soap, and dry well. This stimulates blood flow and ensures that the puncture site is clean. " triggering the lancet to obtain blood 4.2 You can perform all of these functions using just one hand, as to activate a function you only have to press the plunger down. Preparing the finger pricker You use the finger pricker to obtain blood from a fingertip or earlobe, or from other (alternative) sites. If you wish to obtain blood from alternative sites (such as the base of the thumb, forearm, upper arm, calf or thigh), you must replace the normal black cap on the finger pricker with a special, transparent AST cap (which is included in the pack or can be obtained by calling the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1800 709600 (Ireland)). Please read the instructions for use that come with the AST cap before you use blood from alternative sites to test blood glucose. 70 " ejecting the used lancet Testing blood glucose To obtain blood you first need to insert a lancet and then set the penetration depth. Testing blood glucose 71 4 Notes 4.2.1 Undocking the finger pricker from the meter The Accu-Chek Softclix Plus finger pricker is intended only for patient self-monitoring by a single person. The finger pricker must not be used on more than one patient due to the risk of infection. If you wish to use the finger pricker undocked from the meter, detach it as follows: Healthcare professionals testing blood glucose in a multi-patient setting must not use the Accu-Chek Softclix Plus finger pricker to collect blood and should therefore remove the finger pricker from the meter. The finger pricker may be replaced with a blanking plate (see Chapter 10.1). / 0 Only use Accu-Chek Softclix lancets in your Accu-Chek Softclix Plus finger pricker. Using any other lancets may damage the finger pricker or impair its function. This may result in injury. Push the slide button in the direction indicated by the arrow (1) and hold it there. Withdraw the finger pricker in the direction indicated by the arrow (2). 72 Testing blood glucose Testing blood glucose 73 4 4.2.2 Docking the finger pricker onto the meter 4.2.3 Inserting the lancet 4 Hold the meter so it is horizontal, with the recess for docking the finger pricker pointing upwards. Remove the cap from the finger pricker. Place the flat face of the finger pricker on the lower end of the recess, with the plunger facing towards the slide button. Slide the finger pricker forward along the meter in the direction indicated by the arrow, until it locks with an audible CLICK. The guides along the inside of the recess must engage with the grooves along the finger pricker. Slide a new lancet into the lancet holder, and push it in until you hear it CLICK into place. 74 Testing blood glucose Testing blood glucose 75 Notes Dropping the finger pricker with a lancet inserted may loosen the lancet in its holder. In that case the lancet is no longer properly lodged and cannot be used to obtain blood. In rare cases the lancet may even protrude from the cap. In a case such as this you might injure yourself on the lancet. Therefore take great care not to touch the front of the cap. Should you drop the finger pricker, please pick it up with care. Remove the cap from the finger pricker. Take care to avoid the lancet so as not to injure yourself. Always eject and dispose of the lancet if the finger pricker has been dropped (see Chapter 4.5). Afterwards, re-attach the cap without inserting a lancet. Press the plunger all the way down twice. Only then insert a lancet again. Remove the protective cap from the lancet with a twisting motion. / 0 i For blood collection, the cap must be on the finger pricker. Without this cap, the finger pricker cannot be primed, nor can the lancet be triggered. Instead, the lancet is ejected when you press the plunger. Press the cap back on the finger pricker. The locating notch in the cap (1) must be directly aligned with the locating line on the finger pricker (2). The cap snaps into place with an audible CLICK. 76 Testing blood glucose Testing blood glucose 77 4 4.3 Testing blood glucose Notes 4.3.1 Turning the meter on i While the display test is running, you may press the Test button to turn the meter off again. If you do, a test strip is not advanced. i If additional lines appear during the display test or parts of symbols are missing, please contact the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1800 709600 (Ireland). If the numeric field (mmol/L meter) or (mg/dL meter) is affected, the meter may not show your test results correctly. Press the Test button to turn the meter on. Following the display check (see Chapter 2.2.2) a test strip is automatically advanced and the test strip symbol and drop symbol flash in the display. You now have about 5 minutes in which to draw up blood with the test strip. 78 Testing blood glucose Testing blood glucose 79 4 4.3.2 Obtaining blood 4 All the fingertips and both the earlobes are suitable for obtaining blood. We recommend obtaining capillary blood from the side of the fingertip, as this causes the least amount of pain. You can choose the penetration depth from a possible 11 settings ranging from 0.5 to 5.5. Your chosen penetration depth is visible in the window, e.g.: Rotate the Comfort Dial (cap) until you reach your chosen setting. The cap snaps into place at each penetration depth setting. We recommend a low setting (e.g. 2) if you are using the finger pricker for the first time. To obtain blood you first need to prime the finger pricker. The larger the number, the greater the penetration depth. The half-settings – e.g. 2.5 – are identified by a dot. The setting 2.5 is set when the dot is between 2 and 3 in the window. For technical reasons the setting 5.5 is not identified by a dot. Setting 5.5 is set when you rotate the cap beyond setting 5 and the cap snaps into place. Press the plunger all the way down. The plunger returns about a third of the way. The finger pricker is now primed. 80 Testing blood glucose Testing blood glucose 81 Notes Use a new lancet each time you obtain blood. This not only reduces the risk of infection but also helps ensure virtually painfree blood sampling. Do not prime the finger pricker until you are ready to collect blood. Keeping the finger pricker in this primed state can cause parts to become misshapen through tension, impairing its operation. i Firmly press the finger pricker against the chosen puncture site. The amount of blood that emerges at the puncture site depends on the penetration setting and the pressure used to hold the finger pricker against the skin. If the amount of blood you obtain is too small, try again, applying more pressure this time. If you still obtain insufficient blood, repeat the procedure with progressively deeper settings. If too much blood emerges, reduce the penetration depth. You will feel the slightly raised ring against your skin. This is the pinhole through which the tip of the lancet emerges. Press the plunger all the way down. This triggers the lancet, which penetrates the skin. Using gentle pressure, massage the finger towards the fingertip to encourage a drop of blood to form. 82 Testing blood glucose Testing blood glucose 83 4 4.3.3 Drawing up blood with the test strip 4 Wait until the test strip symbol and drop symbol flash in the display and the meter beeps (only when the beep tone is turned on). Hold the meter so the test strip is pointing downwards (see illustration). Immediately after the drop of blood has formed: Hold the tip of the test strip against the drop of blood so the black notch is touching the drop of blood. The test strip draws up blood. Move the finger away from the test strip as soon as the hourglass symbol is displayed and the meter beeps (only when the beep tone is turned on). 84 Testing blood glucose Testing blood glucose 85 The test strip has then drawn up enough blood, and test starts. The hourglass symbol indicates that the meter is busy performing a test. Notes Do not touch the test strip unless you are drawing up blood with it. Residues (e.g. of food, drinks or skin cream) on the skin can find their way onto the strip and may produce incorrect results. Incorrect results can cause the wrong therapeutic decision to be taken and so produce adverse health effects. Testing is complete after approx. 5 seconds. The result is displayed and the meter beeps (only when the beep tone is turned on). At the same time the meter automatically saves the result to memory. Wipe the puncture site with a clean, dry tissue. We recommend covering the puncture site to keep dirt out. 86 Testing blood glucose Take care not to bend the test strip either before or while you draw up blood. Do not bend or move the test strip while the test is in progress. Bending or moving the test strip can produce an incorrect result or cause error message E-5 (see Chapter 12.2) to be displayed. Allowing the test strip to draw up blood too early, i.e. before the test strip symbol and drop symbol flash, can produce an incorrect result or cause error message E-5 (see Chapter 12.2) to be displayed. Turn the meter off with the Test button so as to eject the test strip (see Chapter 4.4), and dispose of the test strip. Repeat the blood glucose test with a new test strip. Testing blood glucose 87 4 Always hold the meter so the test strip is pointing downwards when you are drawing up blood with the test strip. If you hold it so the test strip is pointing upwards or sideways or you put the meter down on a surface with the test strip still in it, blood can enter the meter and contaminate it. i 88 i If the test does not start despite the fact that you have held the drop of blood against the test strip, the test strip drew up too little blood. In this case you can, within a certain period, draw up more blood with the test strip (see the package insert that came with the test strip drums). i If the meter beeps not once but several times when displaying the result, either the hypo indicator is turned on and the result is below the limit (see Chapter 3.10) or Acoustic Mode is turned on (see Chapters 3.3 and 6). As soon as the test strip symbol and drop symbol flash in the display, you have approx. 5 minutes to draw up blood with the test strip. If you have not drawn up blood within this time, i.e. testing has not started, the meter turns off automatically. In this case, press the Test button so as to eject the test strip (see Chapter 4.4), and dispose of the test strip. Start the blood glucose test again with a new test strip. Testing blood glucose Testing blood glucose 89 4 4.4 Notes Ejecting the test strip Hold the meter over a waste bin with the test strip pointing downwards. Always turn the meter off by pressing the Test button, so as to eject the test strip. Do not pull the test strip out. If you do pull the used test strip out, blood can enter the meter and contaminate it. Do not push an ejected test strip back into the test strip drum. This includes any unused test strips that you have ejected by accident. These test strips can produce incorrect results. Incorrect results can cause the wrong therapeutic decision to be taken and so produce serious adverse health effects. i If you do not turn the meter off, it turns off automatically after approximately 60 seconds. The test strip then remains in the meter. The next time you turn the meter on, it ejects this test strip and automatically turns off again. i You can dispose of used test strips with your regular household waste. Press the Test button to turn the meter off. The used test strip drops out. Before the meter turns off, it shows you the number of test strips remaining in the drum (see Chapter 2.3.2). 90 Testing blood glucose Testing blood glucose 91 4 4.5 Ejecting the used lancet If the lancet does not drop out: 4 Keep the plunger pressed down. Remove the cap from the finger pricker. Hold the finger pricker upright above a waste bin. Hook the edge of the white “collar” of the cap behind the platform of the lancet. A cut-out area on the inside of the lancet holder makes it easy to hook the lancet platform (see illustration). Use the white collar to pull the lancet out. Press in the plunger until it CLICKS. The lancet drops out. Press the cap back on the finger pricker. 92 Testing blood glucose Testing blood glucose 93 Notes 4.6 Make sure the lancet has dropped out. Inadvertently leaving the lancet in the finger pricker may result in personal injury. Carefully dispose of used lancets so that the needles cannot cause injury. i You must remove the cap to eject the lancet. If you leave the cap in place, pressing the plunger will prime the finger pricker. Symbols you see before, during or after testing and what they mean 4 You may see the following symbols displayed before, during or after a test. For further information please see Chapter 12.1.

You do not need to save the results manually. The meter automatically saves and numbers the results. The most recent result always occupies memory location 1, the preceding one location 2, etc. up to location 500. When all of the locations are occupied and a new test is performed, the result in location 500 is erased, the other results are shifted one place back in time, and the most recent result is saved in memory location 1. In addition to the result, the time and the date, your meter also saves all other information that is relevant to that test. For example, results flagged as performance checks (see Chapter 7) are displayed together with the bottle symbol . Results obtained at a temperature outside the permitted range are displayed with the thermometer symbol . Please refer to Chapter 12.1 for a complete list of symbols which may be displayed. If your meter has been dropped, that can also lead to implausible results or error messages.

If the memory contains both results that were saved together with the time and date and results that were not saved with this information, then you will see results shown together with their time and date as well as results shown only with their memory location number. i If you turn the meter off with the Test button, it shows you the number of test strips remaining in the drum (see Chapter 2.3.2). i The meter turns off automatically if you have not pressed a button for 60 seconds. 106 Using the meter as an electronic notebook The meter turns on without advancing a test strip. Following the display check (see Chapter 2.2.2), the most recently saved result is displayed together with the time, date and . is short for memory. Using the meter as an electronic notebook 107 5 Press the M and S buttons at the same time. For each of these three periods you can ask the meter to display the lowest and the highest values. The average of the results from the last 7 days is displayed. 5 / Lowest value 0 Average Highest value / The number of results n used in the calculation is displayed at top left (in this example: 30). 0 The number of days for which the average was calculated is displayed at top right (in this example: 7). Again press the M and S buttons together to move to the other averages. The 7-day average is followed by the 14-day and 30-day averages, and then again by the 7-day average. 108 Using the meter as an electronic notebook When one of the three averages is displayed: Press and hold down the M button to view the lowest value. Press and hold down the S button to view the highest value. As long as you hold the M button or S button down, the lowest blood glucose value (and the highest blood glucose value, respectively) which you obtained within the period in question is displayed along with its time and date. If, for instance, the 7-day average was shown, then the lowest or highest value relates to the last 7 days. Using the meter as an electronic notebook 109 When you release the button, the display reverts to the average. You can exit from the average value display at any time: To do this, press the Test button. Memory location 1 Most recent result saved + Notes 7-day period Lowest value Average Highest value + i Results flagged as performance checks with the bottle symbol are not included in the calculations. i Results shown as being or are not included in the average calculations, but are displayed as the lowest and highest values, respectively. i The meter calculates the average value, the lowest value and the highest value for a period even when the saved results cover a shorter period. Example: tests were only performed in the last 5 days. In addition, either no other results were saved or the results that were saved are more than 30 days old. Consequently the results for the last 5 days are used for calculating the average, the lowest value and the highest value for all three periods (7, 14 and 30 days). 14-day period Lowest value Average Highest value + 30-day period Lowest value 5 The meter turns off. Average Highest value + 7-day period 110 Using the meter as an electronic notebook Using the meter as an electronic notebook 111 i If a large number of results were saved within one period, calculation of the average may take a while. flashes in the display while the calculation is in progress. i If no results were saved in memory for the period in question, three horizontal bars are displayed instead of a numerical value. If, for example, the results are more than 7 days old, the average, lowest value and highest value cannot be calculated for 7 days. i The meter can only perform the necessary calculations as long as the results were stored together with the time and date. If you have not entered the time and date, three horizontal bars are displayed instead of the numerical values. i In the event that you changed the date or time, then performed a test and afterwards re-set the date/time, the meter only includes results it saved in uninterrupted chronological order. If the chronological order was interrupted, the earlier results are ignored. If you have not performed any tests since you made the change, three horizontal bars are displayed instead of a numerical value. 112 Using the meter as an electronic notebook i If the memory contains both results that were saved together with the time and date and results that were saved without this information, the averages and respective lowest and highest values will only be calculated from results saved with the time and date that come chronologically before the first result without the time and date. Example: The meter saved 150 results over a period of 50 days. The result in memory location 51 was saved without the time and date. The results in memory locations 1 to 50, which were saved together with the time and date, cover a 20-day period. For calculation of the 7- and 14-day averages, those results are included that are within the period in question. The 30-day average is calculated from all 50 results, even if these only covered a 20-day period. The results after the result without the time and date (memory location 52 and higher) are no longer available for calculation of averages, even if they were saved with the time and date. i If you turn the meter off with the Test button, it shows you the number of test strips remaining in the drum (see Chapter 2.3.2). i The meter turns off automatically if you have not pressed a button for 60 seconds. Using the meter as an electronic notebook 113 5 5.4 Downloading test results to a PC, handheld computer or a special evaluation system The infrared window is located at the front end of the meter. The meter has an inbuilt infrared window permitting wireless data downloading to a suitably equipped PC, handheld computer (PDA), or special evaluation systems. 5 Roche Diagnostics offers a variety of special hardware and software that extend the integrated notebook functions of your meter. These products enable you and your doctor to manage your data more effectively and, through their graph and table views, make it easier for you to understand your results. Depending on the type of analysis you intend to perform, you will require a special software product and/or special hardware products. For further information please contact the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1800 709600 (Ireland). 114 Using the meter as an electronic notebook Be sure to read the operating instructions supplied with the software and hardware you are using. These will include instructions on how to download your data. Make the receiving end (software product or hardware) ready to download the results. Using the meter as an electronic notebook 115 Position the meter 5-20 cm away from the infrared window of the receiving end. Point the two infrared windows towards one another. If necessary, start the results download at the receiving end (software product or hardware). During the download both arrows flashed alternately. During the download only those results that are new to the receiving end, i.e. those have not yet been downloaded, are sent. With the meter turned off, press the M and S buttons at the same time. The meter turns on. Following the display check (see chapter 2.2.2), the following appears: 116 Using the meter as an electronic notebook Once downloading has finished, the arrows stop flashing and the meter is automatically turned off by the receiving end. If the meter is not turned off, press the Test button to turn it off. Using the meter as an electronic notebook 117 5 " Another device with an infrared source turned on or a strong light source is too close to the two infrared windows. Remove the device or light source and start the download again. Notes i Your results can only be fully analysed if all of the results have been saved together with the date and time, i.e. as long as you have set the date and time. i i The results remain in the meter’s memory following downloading. i If the results download does not occur (the arrows do not start to flash) or was incomplete, the meter turns itself off automatically after approximately 5 minutes. This is what might have happened: " An object, for instance, is blocking communication between the two infrared windows. Remove the object and start the download again. You cannot perform a test while results are being downloaded. " An error occurred at the receiving end. Read the relevant manual(s). i If you already have a hardware or software product from Roche Diagnostics to enable you to transfer and evaluate results, it may not recognize more recent meters, so the results will not be downloaded. You may need a more recent software version for your hardware or software product. In this case please contact the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1800 709600 (Ireland). i Data transfer does not follow the IrDA standard (IrDA stands for Infrared Data Association). " A download error occurred. Start the results download again. " The infrared windows are too far apart or not properly facing one another. Reduce the distance between the two infrared windows to 5-20 cm and position them so they are pointing towards one another. Start the results download again. 118 Using the meter as an electronic notebook Using the meter as an electronic notebook 119 5 6 Acoustic Mode Acoustic Mode is intended for persons who are visually impaired. When Acoustic Mode is turned on, the meter guides you through the blood glucose test using beep tones; it also outputs the result as a series of beeps. The meter beeps additionally when the batteries are almost exhausted, the test strip drum is empty, or an error message is displayed. Chapter 3.3 describes how to turn Acoustic Mode on. Visually impaired persons need a sighted person to instruct them in the use of the meter and to assist them with all aspects of its operation. Visually impaired persons must not test their blood glucose without assistance from a sighted person. An intimate knowledge of how results are represented as beeps and how to distinguish results from other beeps is crucial to reliably recognizing the result. The chapters that now follow explain the beep tones in detail. In addition, training software (the BeepLearn-Programm) to help you interpret results announced in the form of beeps is available on CD from the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1800 709600 (Ireland). Practise listening to beeps from actual tests or from the training software together with a sighted person until you can clearly recognize and interpret the results and other beeps you will hear. There are two types of beep tone, differing in pitch. Warnings have a higher tone (Tone 2, represented below as — ) than the other beep tones (Tone 1, represented below as — ). The following table shows which tone sounds for which event. Turning on Chapter 6.1 Meter ready to test Chapter 6.2 Start of test Chapter 6.2 Announcement of the result Chapters 6.3 and 6.4 Signal that results are due to be announced Chapters 6.3 and 6.4 Announcement of an error message Chapters 6.2 and 6.5 Notification that the batteries are almost exhausted Chapter 6.5 Notification that the drum is empty Chapter 6.5 6 Tone 1 Tone 2 (warning) If you have problems determining the results from the beeps, you should not use Acoustic Mode. 120 Acoustic Mode Acoustic Mode 121 6.1 Beep tones at power-on 6.2 Beep tones during testing When Acoustic Mode is set to on, you hear a long beep ( — ) when you turn on the meter. Following the power-on beep and the 1 – 2 – 3 sequence of beeps, you will hear the following while you test: This is irrespective of which button you use to turn the meter on: " a single beep when the meter is ready to test so you can let the test strip draw up blood or control solution, " the Test button in order to perform a test (see Chapter 4.3.1) " a single beep when the test strip has drawn up sufficient blood or control solution and the test is starting, " the S button in order to change settings (see Chapter 3) " the M button in order to retrieve results from memory (see Chapter 5) " several beeps each time the meter displays an error message (see Chapter 6.5). " the M and S button in order to send results (see Chapter 5.4) If you press the Test button or M button to turn the meter on, you first hear the long power-on beep followed by 6 further beeps spaced as 1 – 2 – 3 ( – – – – – – ). 6.3 Announcement of the result following a test In Acoustic Mode, whenever your meter displays a result following a blood glucose test, it also announces the result as a series of beeps. The result is not treated as an entity, but is broken down into individual digits. Examples: " The result 7.6 mmol/L is announced as 0 – 7 – decimal point – 6. " The result 138 mg/dL is announced as 1 – 3 – 8. 122 Acoustic Mode Acoustic Mode 123 6 Each digit is represented by the corresponding number of beeps; e.g. 4 beeps for the number 4 ( – – – – ). Zero is represented by a long beep ( — ). The result is announced three times in succession. Each result is preceded by two short beeps ( - - ) . Altogether, therefore, you hear: - result - - result - - result. mg/dL meters First the hundreds are announced, then the tens, and finally the units. There is a short pause between each group of beeps. The hundreds are always announced, even when the result is below 100. The hundreds in this case are represented by 1 long beep, signifying zero. Examples: mmol/L meters First the tens are announced, then the units, then the decimal point and finally the tenths. There is a short pause between each group of beeps. The tens are always announced, even when the result is below 10. The tens in this case are represented by 1 long beep, signifying zero. The decimal point is represented by 1 very short beep ( . ). Examples: " The result 13.8 mmol/L is announced as follows: 1 beep – pause – 3 beeps – pause – 1 very short beep – pause– 8 beeps ( – – – – . – – – – – – – – ) " The result 4.0 mmol/L is announced as follows: 1 long beep (for 0 tens) – pause – 4 beeps – pause – 1 very short beep – pause – 1 long beep ( — – – – – . — ) 124 Acoustic Mode " The result 180 mg/dL is announced as follows: 1 beep – pause – 8 beeps – pause – 1 long beep ( – – – – – – – – – — ) " The result 72 mg/dL is announced as follows: 1 long beep (for 0 hundreds) – pause – 7 beeps – pause – 2 beeps ( — – – – – – – – – – ) Results that are lower than 0.6 mmol/L or 10 mg/dL and are displayed as are announced acoustically as 0 – 0 – 0 and 0 – decimal point – 0, respectively. Results that are higher than 33.3 mmol/L or 600 mg/dL and are displayed a are announced acoustically as 9 – 9 – 9 and 9 – 9 – decimal point – 9, respectively. Acoustic Mode 125 6 Notes Note i If the 7-day average cannot be calculated, three horizontal bars are displayed. This is signalled acoustically with 3 long beeps representing 3 zeroes ( — — — ). i If you press the M button to turn the meter on, you first hear the long power-on beep followed by the beep sequence 1 – 2 – 3 and then the most recent result. If the result that was most recently saved is flagged by the bottle symbol as being a performance check result (see Chapter 7), it is announced in the same way as any blood glucose test result. There is no acoustic signal to identify it as a performance check result. Likewise, there is no acoustic signal to identify a result flagged by an asterisk as being a special result (see Chapter 4.7). i Only the average for the last 7 days is announced acoustically. The lowest and highest results within this period are not announced acoustically. The 14 and 30-day averages and the lowest and highest results within these two periods (see Chapter 5.3) are not announced acoustically in Acoustic Mode, but only displayed. i If no result has been saved, just three horizontal bars displayed. There is no acoustic announcement. i 6.4 Information or warnings in the form of symbols (e.g. drum symbol or symbol, see Chapter 12.1) that are displayed together with the result are not announced acoustically. Announcement of results and average values from memory Only the last (most recent) result that was saved can be announced acoustically. are The announcement follows the same pattern as any result that is announced directly following a test. 126 Acoustic Mode Acoustic Mode 127 6 7 6.5 Announcement of warnings and error messages Checking your meter To ensure your results are always dependable, you should periodically check the performance of your meter. When the batteries will soon be exhausted or the last test strip in a drum has been used, The meter issues an acoustic warning. This consists of two short beeps sounded three times in succession ( - - - - - - ). Do this by performing a performance check using the Accu-Chek Compact Autocontrol control solutions, each time The warning is given at different times. " after you have replaced the batteries. " Batteries are almost exhausted (the battery symbol is displayed, see Chapter 9): This acoustic warning is sounded when you turn the meter on. " after your meter has displayed the bottle symbol perform a performance check, " You have used the last test strip in the drum (H> and drum symbol flash, see Chapters 2.3 and 12.2): The acoustic warning is given after you have pressed the Test button to turn the meter off. If error messages ( with a number or the , see Chapter 12.2) are displayed, these are announced by two short beeps sounded four times in succession ( - - - - - - - - ). This sequence is sounded only once and is not repeated. The same sequence of beeps is sounded for all error messages, i.e. they are not differentiated acoustically. 128 Acoustic Mode " after you have opened a new pack of test strip drums, 7 prompting you to " after you have cleaned the measuring window of the meter, " if your result does not agree with how you feel. You can obtain control solution free from Roche Diagnostics by calling the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1800 709600 (Ireland). Checking your meter 129 7.1 7.2 What you need To perform a performance check you need the following items: Performing a performance check Read the package insert that came with the control solutions. " meter with a test strip drum inserted " Accu-Chek Compact control solution Autocontrol G1 (low glucose concentration) or Autocontrol G2 (high glucose concentration) " Concentration table for the control solutions (see label on the container the test strip drum came in). 7 Press the Test button to turn the meter on. Note i 130 The concentration table for the control solutions can be found on the peel-off label attached to the drum container. When conducting the performance check, always make sure that the peel-off label with the concentration table belongs to the test strip drum that is currently in the meter. Checking your meter Following the display check (see Chapter 2.2.2) a test strip is automatically advanced, and the test strip symbol and the drop symbol flash in the display. Checking your meter 131 You now have about 5 minutes in which to draw up control solution with the test strip. Take a bottle of control solution. Open it and wipe the tip of the dropper with a clean, dry paper towel in order to remove any dried-on residues. Invert the vial and hold it downwards at an angle. Squeeze it gently until a small drop is suspended from the tip. 7 Hold the meter so the test strip is pointing downwards (see illustration). Apply the drop to the surface of a clean, easily washable object made of glass, porcelain or stainless steel (e.g. a plate or spoon). Hold the tip of the test strip to the drop of control solution. 132 Checking your meter Checking your meter 133 The test strip draws up the control solution through the black notch. Immediately after the result is displayed: Move the test strip away from the control solution as soon as the hourglass symbol is displayed and the meter beeps (provided the beep tone is turned on). Compare the result with the concentration table printed on the peeloff label attached to the drum container. The result must be within the concentration range stated. The test strip has then drawn up enough control solution, and testing starts. The hourglass symbol indicates that the meter is busy performing a test. The meter automatically detects that the test strip has drawn up control solution. The bottle symbol appears additionally in the display when the test starts. The concentration table has two rows and two columns. Rows 1 and 2 contain concentration data for the two different control solutions, G1 and G2; the columns are for the two different units of measurement, mmol/L and mg/dL. Make sure you compare the result with the concentration data stated for the control solution you used and the unit of measurement your meter displays. Accu-Chek® Compact Autocontrol Testing is complete after approx. 5 seconds. The result is displayed and the meter beeps (provided the beep tone is turned on). The meter at the same time saves the result together with the bottle symbol . The saved result is thus recognizable as being a performance check result. mmol/L mg/dL G1 1.7-3.4 31-61 G2 7.1-9.6 127-172 Unit of measurement The figures shown are for illustration only Control solution used 134 Checking your meter Checking your meter 135 7 Subsequently hold the meter directly above a waste bin with the test strip pointing downwards. Press the Test button to turn the meter off. i You can dispose of empty or only partly used bottles of control solution together with your regular household waste. Please refer also to the notes in Chapters 4.3 and 4.4. The used test strip drops out. Before the meter turns off, it shows you the number of test strips remaining in the drum (see Chapter 2.3.2). Wipe the tip of the dropper with a clean, dry paper towel and close the bottle tightly. Notes i The control solution you apply to a washable object must come from a suspended drop. Do not use the drop if it has run down the outside of the tip of the dropper. This may lead to results that are too high. i Control solution that is to be drawn up by the test strip must just have been freshly applied to the object. The control solution must not be left exposed on the surface for any length of time, or it may give results that are too high. i Results flagged as performance checks with the bottle symbol are not included in the calculation of averages and lowest and highest results. 136 Checking your meter 7.3 Possible causes of error during the performance of performance checks If the result is outside the stated concentration range, perform a second performance check. If the result of this second check is outside the concentration range as well, please check the following points: Did you perform the performance check as described above? yes Did you wipe the tip of the dropper before you applied control solution to the surface of the washable object? yes Did you use a suspended drop of control solution? yes Was there prolonged contact between the control solution and the washable object? no Did you bend the test strip either before or while you were drawing up control solution? no Did you wait for the test strip symbol and drop symbol to flash yes in the display before drawing up control solution with the test strip? Checking your meter 137 7 Did you bend or move the test strip while the test was in progress? no Did you compare the result with the concentration data specifically relating to the control solution you used? yes Does the concentration table belong to the test strips that are currently in the meter? yes Did you perform the test within the correct temperature range (+10 °C to +40 °C)? yes Has the use-by-date for the control solution or the test strips expired (see label on the bottle and the test strip drum next to the symbol)? no Has the 90-day use-by period for the test strip drum expired in the (see Chapter 2.3.1 and possibly the clock symbol meter’s display)? no Are the test strip guide and measuring window clean? yes Have you observed the proper storage conditions for the meter, test strips and control solutions (see Chapter 11 and the package inserts that came with the test strips and control solutions)? yes Has the control solution been open for less than three months? Once opened, control solutions are only stable for three months and must not be used after this period. yes 138 Checking your meter If you give the responses as specified to all these questions and the results are still outside the stated concentration range, please call the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1800 709600 (Ireland). If your meter has been dropped, that can also lead to implausible results or error messages. If it has, again please call the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1800 709600 (Ireland). Note If a performance check produces results that are outside the stated concentration range, it is no longer certain that the meter and test strips are functioning properly. Blood glucose tests may then deliver incorrect results. Incorrect results can cause the wrong therapeutic decision to be taken and so produce serious adverse health effects. Checking your meter 139 7 8 Cleaning the meter and finger pricker 8.1 Cleaning the meter Do this as follows: Your meter uses an optical measuring method that relies heavily on all of its components being clean. Owing to the way the test strip works, the meter does not normally come into direct contact with blood or control solution. Regular cleaning is therefore largely unnecessary. In the event of the meter becoming soiled through improper use, cleaning it may become necessary. If the meter is on, press the Test button to turn it off. Wait for the motor to stop. Wipe away any soiling from the housing or display with a cloth lightly moistened with cold water or 70 % ethanol. Clean the test strip guide and measuring window thoroughly if " the test strip guide has become visibly soiled, 8 Wipe the test strip guide with a cotton swab lightly moistened with cold water or 70 % ethanol. " error message E-5 is displayed (see Chapter 12.2) and the soiled measuring window is the cause. Hold the meter in your right hand and place the thumb of your left hand into the recess below the drum compartment cover. Then pull the drum compartment cover with your fingers slightly to the front and lift it up. 140 Cleaning the meter and finger pricker Cleaning the meter and finger pricker 141 Notes Use only cold water or 70 % ethanol to clean the meter. Any other cleaning agents may damage the meter or impair its measuring function. Use a lightly moistened cloth or a lightly moistened cotton swab. Do not spray anything onto the meter and do not immerse it in the cleaning liquid. Doing so may damage the meter’s internal components and stop it from working properly. Make sure that no liquid enters the meter. Avoid scratching the measuring window, as doing so could impair its measuring function. Wipe the measuring window and the area surrounding it with a cotton swab lightly moistened with cold water or 70 % ethanol. Remove any fluff or lint that may remain. Allow areas you have wiped time to dry thoroughly. Fold the drum compartment cover down and press it shut. There will be an audible CLICK. i Make sure that the drum compartment cover is tightly closed. If it is not properly closed, the meter will not turn on when you press the Test button. Healthcare professionals using the meter to test several patients’ blood glucose must also read the directions in Chapter 10.3 relating to disinfection. Perform a performance check (see Chapter 7). 142 Cleaning the meter and finger pricker Cleaning the meter and finger pricker 143 8 9 8.2 Cleaning the finger pricker Clean your finger pricker regularly to keep it in good working condition. If any blood gets on it, always wipe this away immediately. Clean the outside of the finger pricker only. Wipe it once a week with a cloth lightly moistened with 70 % ethanol or 70 % isopropanol (available from your pharmacist). In addition, thoroughly wipe the inside of the cap using a cotton bud lightly moistened with one of the two cleaning fluids. Changing the batteries When the battery symbol first appears in the display, the batteries are running low. With these batteries you can perform about 50 more tests. However, we recommend that you replace the batteries as soon as possible. By then the batteries will have been heavily drained, and changeable conditions (e.g. cold surroundings) can affect their performance even further. If the meter is on, press the Test button to turn it off. 9 Notes After cleaning, allow the finger pricker time to dry thoroughly. Never dip the finger pricker in cleaning liquid. Doing so may damage the internal parts of the finger pricker so affecting its operation. Use only 70 % ethanol or 70 % isopropanol to clean the finger pricker. Other cleaning agents may attack the plastic and stop the finger pricker from operating properly. Press lightly on the battery compartment cover and slide it in the direction of the arrow. Lift off the cover. Remove the used batteries. 144 Cleaning the meter and finger pricker Changing the batteries 145 Notes i A fresh pair of batteries has enough power either for about 1000 tests or for one year’s worth of tests. If you have changed the brightness of the display to level 3 (high) or set Acoustic Mode to on, the battery life will be shorter. i When you replace the batteries, your results always remain saved. i The year, time and date settings only remain saved as long as Insert two new batteries (type AAA, LR 03, AM 4 or micro). " you do not take longer than two minutes to change the batteries, The minus (-) ends of the batteries must match up with the minus marks in the battery compartment. " you do not press any button while the batteries are not inserted, Re-attach the battery compartment cover. " you do not open the drum compartment while there are no batteries inserted. The three hooks on the underside of the cover must engage with the slots along the edge of the battery compartment. The cover is then just loosely held in position. Slide the battery compartment cover back into place. It locks with an audible CLICK. 146 Changing the batteries " you turn the meter off before removing the batteries. If one of the above conditions is not met you will need to re-enter the year, time and date. If you do not enter the year, time and date, all future results will be displayed and saved without the time and date. In that case Changing the batteries 147 9 the test results saved in memory will be numbered consecutively so you can still recognize the order in which they were saved (see Chapter 5.2). i Never throw batteries into a fire. This is dangerous because they may explode. If the year, time and date have been lost, the meter rotates the drum in order to re-read the bar code. i Remove the batteries if you will not be using your meter for any length of time. When you insert the batteries again, remember to set the year, time and date. You can also use rechargeable NiMH batteries. If you do, please note the following: i Think of the environment. Dispose of used batteries sensibly. " The number of tests you can perform with recharged batteries is considerably less than with ordinary batteries. 9 " To be ready to test at any time, you need to keep two rechargeable batteries in reserve which you can charge while the first pair are in the meter. " Recharged batteries lose their charge during storage. " When the battery symbol first appears, you can perform significantly fewer than 50 further tests. With old and exhausted rechargeable batteries you may not be able to perform even one more test. " The performance and useful life of rechargeable batteries depends to a large extent on the quality of the battery charger you are using. " Owing to the higher power consumption, we advise against using rechargeable batteries if the brightness of the display is set to level 3 (high) or if Acoustic Mode is set to on. 148 Changing the batteries Changing the batteries 149 10 Blood glucose testing in a multi-patient setting – Information for healthcare professionals Only healthcare professionals are allowed to perform blood glucose tests on more than one patient using the same Accu-Chek Compact Plus meter. Any patient with an infection or suffering from an infectious disease and any patient who is a carrier of a multiresistant organism must be assigned his/her own meter. This applies also if a patient is suspected of being one of the above. For as long as the suspicion exists, the meter must not be used to test any other patient. When using the meter always follow the recognized procedures for handling objects that are potentially contaminated with human material. Practise the hygiene and safety policy of your laboratory or institution. The Accu-Chek Softclix Plus finger pricker is intended only for patient self-monitoring by a single person. It must not be used to collect blood in a multi-patient setting as it does not incorporate any features to guard against cross-infection. Also, to stop your meter becoming contaminated, please follow the directions printed on the next few pages. Notes Patients and healthcare workers are potentially at risk of becoming infected when the same Accu-Chek Compact Plus meter is used to test blood glucose in several patients. Any object coming into contact with human blood is a potential source of infection (see: Clinical and Laboratory Standards Institute: Protection of Laboratory Workers from Occupationally Acquired Infections; Approved Guideline – Third Edition; CLSI document M29-A3, 2005). 150 Blood glucose testing in a multi-patient setting Healthcare professionals testing blood glucose in a multi-patient setting must not use the Accu-Chek Softclix Plus finger pricker to collect blood and should therefore remove the finger pricker from the meter. The finger pricker may be replaced with a blanking plate (see Chapter 10.1). For healthcare professionals we recommend the Accu-Chek Safe-T-Pro Plus or Accu-Chek Safe-T-Pro Uno disposable finger prickers. i The hypo indicator level may vary from person to person. Therefore we recommend leaving the hypo indicator function turned off when using the meter in a professional setting. Blood glucose testing in a multi-patient setting 151 10 10.1 Replacing the finger pricker with a blanking plate Undock the finger pricker from the meter as follows. Instead of the finger pricker you can use a blanking plate which is available from the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1800 709600 (Ireland). / 0 10 Push the slide button in the direction indicated by the arrow (1) and hold it there. Slide the finger pricker out in the direction indicated by the arrow (2). Hold the meter so it is horizontal, with the recess for docking the finger pricker pointing upwards. Slide the blanking plate over the recess from the left along the meter in the direction indicated by the arrow. The guides along the inside of the recess must engage with the grooves along the blanking plate. The blanking plate is properly attached when it locks into place with an audible CLICK. 152 Blood glucose testing in a multi-patient setting Blood glucose testing in a multi-patient setting 153 10.2 Testing blood glucose Correct Wear protective gloves. Wash or disinfect the patient’s finger and allow it to dry thoroughly. The drop of blood does not spread so easily over dry skin. Use only a finger pricker that is approved for use by healthcare professionals. Use a finger pricker with adjustable penetration depth settings. Select a penetration depth to suit the patient’s skin type. Start with a shallow depth setting. Drop of blood approx. 1.5 μL Select a puncture site along the side of a fingertip. Hold the meter with the test strip pointing downwards (see illustration). Turn the finger so the chosen puncture site is facing upwards, and keep it facing upwards. The drop of blood cannot then spread so easily. Immediately after the drop of blood has formed: Hold the tip of the test strip against the drop of blood so the black notch is touching the drop of blood. The test strip draws up blood. Prick the side of the fingertip. Move the test strip away from the drop of blood as soon as the hourglass symbol is displayed and the meter beeps (only when the beep tone is turned on). The test strip has then drawn up enough blood, and test starts. Using gentle pressure, massage the finger towards the fingertip to encourage a drop of blood to form. A proper but nevertheless small drop of blood (approx. 1.5 μL) must form. When the result is displayed, hold the meter upright over a waste bin and press the Test button to turn it off. The used test strip drops out. 154 Blood glucose testing in a multi-patient setting Blood glucose testing in a multi-patient setting 155 10 Notes Residues of water or disinfectant on the skin can dilute the drop of blood and so produce false results. Always hold the meter so the test strip is pointing downwards when you are drawing up blood with the test strip. If you hold it so the test strip is pointing upwards or sideways or you lay the meter down with the test strip still in, blood can enter the meter and contaminate it. Hold the meter with the test strip pointing downwards until the result is displayed (measuring time approx. 5 seconds) and you have ejected the test strip. Always turn the meter off by pressing the Test button, so as to eject the test strip. Do not pull the test strip out. If you do pull the used test strip out, blood can enter the meter and contaminate it. Dispose of used lancets or disposable finger prickers and used test strips according to local hygiene and safety regulations. i Wrong Test strip pointing upwards The test strip cannot properly draw up blood that has spread over the skin. Wrong To test blood glucose you require approximately 1.5 μL of blood. Avoid producing large drops of blood on the patient’s finger. Where the drops of blood are too large, the meter may come into contact with the blood. Wipe off any large drops of blood. Test using the drop of blood that forms again at the puncture site. 10 Drop of blood that has spread i If you collect blood from an earlobe, be sure that the blood is on top and not hanging from the earlobe. Hold the earlobe or position the patient so the puncture site is on top. Wrong Drop of blood too large 156 Blood glucose testing in a multi-patient setting Blood glucose testing in a multi-patient setting 157 10.3 Disinfecting the meter The Accu-Chek Compact Plus meter may be disinfected. Disinfection is performed according to the degree of soiling (see “When to disinfect”). What to disinfect The following parts of the meter may become contaminated: Hold the meter in your right hand and place the thumb of your left hand into the recess below the drum compartment cover. Then pull the drum compartment cover with your fingers slightly to the front and lift it up. Once you have opened the drum compartment cover, you will see beneath it the small measuring window / and have access to the lower edge of the drum compartment cover 0. " the area around the test strip guide / 10 " the lower edge of the drum compartment cover " the measuring window 0 " the housing In order to disinfect the lower edge of the drum compartment cover and measuring window, you need to open the drum compartment cover. First make sure the meter is turned off. 158 Blood glucose testing in a multi-patient setting Blood glucose testing in a multi-patient setting 159 Cotton buds, wipes and cloths lightly moistened with disinfectant are all suitable for disinfecting the meter. When to disinfect " Each time after you have tested a patient’s blood glucose: Allow areas you have wiped time to dry thoroughly. wipe the area around the test strip guide. Remove any fluff or lint that may remain. If you find blood on the cloth, wipe also the test strip guide itself and the measuring window. Fold the drum compartment cover down and press until it closes. It locks with an audible CLICK. Ensure that the drum compartment cover is properly closed. " If there is blood on the meter: wipe the meter. " If blood has entered the meter: Notes The test strip guide and measuring window must always be kept clean. When you turn the meter on to perform a test, the test strip is advanced over the measuring window and out through the test strip guide. Any residues of blood remaining on the measuring window or in the test strip guide may get onto the test strip and contaminate it. Make sure that no liquid enters the meter. Avoid scratching the measuring window, as scratches could impair its measuring function. wipe the area around the test strip guide, the lower edge of the drum compartment cover and the measuring window. Allow areas you have wiped time to dry thoroughly. The meter, test strip guide and measuring window must be thoroughly cleaned and disinfected at least once a day after use. Carefully check all recesses, grooves and gaps, as well as the blanking plate. Do not spray anything onto the meter and do not immerse it in liquid. Doing so may damage the meter’s internal components and stop it from working properly. 160 Blood glucose testing in a multi-patient setting Blood glucose testing in a multi-patient setting 161 10 11 10.4 Suitable disinfectants Use only disinfectants of proven effectiveness quoted in official guidelines (e.g. Clinical and Laboratory Standards Institute: Protection of Laboratory Workers from Occupationally Acquired Infections; Approved Guideline – Third Edition; CLSI document M29-A3, 2005). Use alcohol-based surface disinfectants with virucidal activity. Suitable agents are those, for instance, based on alcohols, aldehyde cleavers and quaternary compounds*. Use them according to manufacturer’s instructions. Measurement and storage conditions The reliability of your meter and finger pricker as well as the accuracy of your results is influenced by a number of factors. Pay close attention to the following points. A meter that has been dropped can produce false results. 11.1 Temperature range " Without the batteries and without the test strip drum the meter may be stored at between -25 °C and +70 °C. " With the batteries and without the test strip drum the meter may be stored at between -10 °C and +50 °C. At temperatures above +50 °C the batteries could leak and damage the meter. 11 * List of disinfection methods that have been tested in accordance with the “Richtlinien für die Prüfung chemischer Desinfektionsmittel” [Guidelines for testing chemical disinfectants] and the “Anforderungskatalog” [Requirements catalogue] of the DGHM (Deutsche Gesellschaft für Hygiene und Mikrobiologie e V.) [=German Society for Hygiene and Microbiology] based on the DGHM standard methods for testing chemical disinfection methods and have been found to be efficacious by the Desinfektionsmittel-Kommission [=Disinfectants Commission] of the DGHM in collaboration with representatives of the following professional associations: DGKH (Deutsche Gesellschaft für Krankenhaushygiene e. V.) [=German Society for Hospital Hygiene], GHU (Gesellschaft für Hygiene und Umweltmedizin e. V.) [=German Society for Hygiene and Environmental Medicine], DVV (Deutsche Vereinigung zur Bekämpfung der Viruskrankheiten e.V.) [=German Association for the Control of Viral Diseases] and DVG (Deutsche Veterinärmedizinische Gesellschaft e. V.) [=German Veterinary Society] 162 Blood glucose testing in a multi-patient setting At temperatures below -10 °C the batteries do not have enough power to keep the internal clock functioning. " With the batteries and with the test strip drum the meter may be stored at between +2 °C and +30 °C. " For blood glucose tests and performance checks the permitted range is from +10 °C to +40 °C. Measurement and storage conditions 163 " Blood glucose tests may be performed at the limit of the permitted range (between +6 °C and +10 °C or between +40 °C and +44 °C). When the temperature is at the limit of the permitted range, the thermometer symbol flashes in the display. Do not use results obtained at the limits of the permitted temperature range as a basis for making therapeutic decisions. The results may be incorrect. Incorrect results can cause the wrong therapeutic decision to be taken and so produce serious adverse health effects. " Tests cannot be performed at temperatures below +6 °C and above +44 °C. In this event the following message is displayed: Never try to speed up warming or cooling of your meter, e.g. by placing it on a radiator or in a refrigerator. Doing so can damage the meter and cause it to give incorrect results. Incorrect results can cause the wrong therapeutic decision to be taken and so produce serious adverse health effects. Keep the finger pricker without a lancet inserted. Never expose the finger pricker to high temperatures (e.g. in a hot car). High temperatures can cause parts of the finger pricker to become warped, so impairing its operation. 11.2 Light conditions All displayed numbers and symbols appear yellow. Bright light shining on the display may make them difficult to read. Shield the meter if necessary using your body, for instance. " Keep the finger pricker at temperatures between -25 °C and +70 °C. 164 Measurement and storage conditions Keep the meter away from very strong light sources (e.g. direct sunlight, studio lighting, spot lights, etc.). These may interfere with the proper functioning of the meter and cause error messages to be displayed. Measurement and storage conditions 165 11 12 11.3 Humidity Only test blood glucose at a relative humidity of between 20 % and 85 %. Keep the meter and finger pricker at a relative humidity of between 20 % and 85 %. Sudden changes in temperature cause condensation to form in or on the meter. If this happens, do not turn the meter on. Make sure that it returns to ambient temperature slowly. Never keep it in a room that is likely to harbour condensation (e.g. a bathroom). Symbols, error messages and troubleshooting In addition to test results, the time and the date, your meter also displays other symbols and error messages. Some of these routine display messages have already been explained in earlier chapters. Following is a complete summary of all symbols and messages, what they mean and what actions you should take when they appear. When you use your meter, please watch out for any symbols and error messages that are displayed. They provide you with important information. If you do not recognize a symbol or do not understand an error message, please refer immediately to this chapter for an explanation. Otherwise you run the risk of wrongly interpreting your results. On some of the pages that follow you will see a double arrow .

The system is calibrated with venous blood containing various levels of glucose. The reference values are obtained using the hexokinase method. The method comparison was conducted by comparing the results from the system with those of the hexokinase method with deproteination using an automatic analyzer. The hexokinase method is traceable to an NIST standard (traceability). The Accu-Chek Compact Plus system complies with the requirements of EN ISO 15197. 198 Technical data Technical data 199 13 14 Disposing of the meter 15 System components During blood glucose testing the meter itself may come into contact with blood.

For information about correct disposal please contact your local council or authority. Use only Accu-Chek Compact test strips for testing with the Accu-Chek Compact Plus meter. These are available from your pharmacist. The meter falls outside the scope of the European Directive 2002/96/EC (Directive on waste electrical and electronic equipment). Only use Accu-Chek Softclix lancets in your Accu-Chek Softclix Plus finger pricker. The lancets are available in various pack sizes. Use only Accu-Chek Compact Autocontrol control solutions to perform performance checks on your Accu-Chek Compact Plus meter. If you wish to use blood from alternative sites (such as the base of the thumb, forearm, upper arm, calf or thigh), you need a special, transparent AST cap to obtain blood using the Accu-Chek Softclix Plus finger pricker. It is available through the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1800 709600 (Ireland). For healthcare professionals we recommend the Accu-Chek Safe-T-Pro Plus or Accu-Chek Safe-T-Pro Uno disposable finger prickers. 14 15 200 Disposing of the meter System components 201 16 17 Patents Accu-Chek Compact Plus Meter EP 732 590; EP 738 666; EP 742 436; EP 1 189 064; US 5,463,467; US 5,720,924; US 5,863,800; US 6,707,554; US 6,475,436; WO 2004/003549 Accu-Chek Softclix Plus Finger pricker US 4,924,879; US-2004-0092996; US 2005-00908580; US Re. 35,803 16 Patent information Roche has been granted patent protection in the USA for the Accu-Chek Softclix Plus finger pricker and its use in combination with Accu-Chek Softclix and Accu-Chek Softclix XL lancets (US Patents 4,924,879 and Re. 35,803).
